"The Diatoms of the United States Exclusive of Alaska and Hawaii," authored by Ruth Patrick and Charles W. Reimer, is a seminal work published by The Academy of Natural Sciences of Philadelphia in 1966. This second printing is part of the Monographs series, specifically Number 13, and provides an in-depth exploration of diatom species within the continental United States, excluding Alaska and Hawaii. The book is a crucial resource for students and professionals in the fields of biology and limnology, offering detailed classifications of Fragilariaceae, Eunotiaceae, Achnanthaceae, and Naviculaceae. Ruth Patrick and Charles W. Reimer, both respected figures in the study of freshwater ecosystems, provide comprehensive insights into the diversity and ecological significance of diatoms. This edition is particularly valuable for collectors and researchers due to its specialized focus and academic pedigree. The book is in good condition, with library markings indicating its previous use in a library setting, but retains its integrity as a reference work.
